5## Build
6
7Install Rust:
8
9```bash
10curl https://sh.rustup.rs -sSf | sh
11```
12
13Install required tools:
14
15```bash
16./scripts/init.sh
17```
18
19Build Wasm and native code:
20
21```bash
22cargo build
23```
24
25## Run
26
27### Single node development chain
28
29You can start a development chain with:
30
31```bash
32cargo run -- --dev
33```
34
35Detailed logs may be shown by running the node with the following environment variables set: `RUST_LOG=debug RUST_BACKTRACE=1 cargo run -- --dev`.
36
37### Multi-node local testnet
38
39If you want to see the multi-node consensus algorithm in action locally, then you can create a local testnet with two validator nodes for Alice and Bob, who are the initial authorities of the genesis chain that have been endowed with testnet units.
40
41Optionally, give each node a name and expose them so they are listed on the Polkadot [telemetry site](https://telemetry.polkadot.io/#/Local%20Testnet).
42
43You'll need two terminal windows open.
44
45We'll start Alice's substrate node first on default TCP port 30333 with her chain database stored locally at `/tmp/alice`. The bootnode ID of her node is `QmRpheLN4JWdAnY7HGJfWFNbfkQCb6tFf4vvA6hgjMZKrR`, which is generated from the `--node-key` value that we specify below:
46
47```bash
48cargo run -- \
49  --base-path /tmp/alice \
50  --chain=local \
51  --alice \
52  --node-key 0000000000000000000000000000000000000000000000000000000000000001 \
53  --telemetry-url ws://telemetry.polkadot.io:1024 \
54  --validator
55```
56
57In the second terminal, we'll start Bob's substrate node on a different TCP port of 30334, and with his chain database stored locally at `/tmp/bob`. We'll specify a value for the `--bootnodes` option that will connect his node to Alice's bootnode ID on TCP port 30333:
58
59```bash
60cargo run -- \
61  --base-path /tmp/bob \
62  --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/QmRpheLN4JWdAnY7HGJfWFNbfkQCb6tFf4vvA6hgjMZKrR \
63  --chain=local \
64  --bob \
65  --port 30334 \
66  --telemetry-url ws://telemetry.polkadot.io:1024 \
67  --validator
68```
69
70Additional CLI usage options are available and may be shown by running `cargo run -- --help`.
